Steel components for a power transmission system sfter coating/polishing with CT-33

Product Description

CT-33 coating systems are inorganically bonded aluminum coatings developed specifically for high and cyclic temperature resistance and for certain corrosion applications in a salt environment. These coatings also feature excellent thermal stability and hardness along with good flexibility and superior adhesion. As service temperature increases, corrosion and oxidation protection also increase providing an optimum temperature range of 900°F to 1600°F for oxidizing environments. Thermal shock characteristics are outstanding, as the coating will remain totally adherent to most metals after repeated cycling between 1100°F and ambient temperature. When polished to a metallic luster, the surface becomes electrically conductive affording sacrificial and vastly improved corrosion protection.

Advantages

• Protects against cyclic corrosion and oxidation in gas turbine applications
• Tested, approved and specified by leading manufacturers of gas turbine engines.
• An alternative to plating on vehicle exhaust systems
• Provides improved resistance to corrosion, erosion, metal fatigue, thermal shock, heat and thermal oxidation
• Provides sacrificial corrosion protection to all steels and to most aluminum alloys
• Provides an aluminization capability without a large capital equipment investment.
• An ideal coating for furnace liners, racks, trays, trays, fans and supports, eliminating the need for more oxidation resistant alloys
• An excellent primer for use in conjunction with numerous coatings and adhesives.
• High temperature corrosion resistance: protection to 1100°F
• High temperature oxidation resistance: protection to 1600°F
• Outstanding thermal shock stability; maintains adhesion after repeated cycling between 1100°F and ambient temperatures
• Superior adhesion
• Excellent hardness and flexibility
• Outstanding salt spray and marine protection
• Polishes to chrome-like finish
• Electrically conductive when polished
• Improved resistance to erosion and metal fatigue
• Easy-to-apply single-component compound
• Water soluble for easy clean-up
  
  

Applications

All CT-33 coatings are suitable for the following applications unless otherwise noted:

• Gas turbines: protects against cyclic corrosion and oxidation; tested, approved and specified by leading manufacturers (CT-33, CT-33M)
• Vehicle exhaust systems: alternative to plating (CT-33M, CT-33H)
• Furnace liners, racks, trays, fans and supports: CT-33 coating eliminates need for more oxidation resistant alloys
• Steels, aluminum: galvanic corrosion resistance
• Primer in conjunction with other coatings/adhesives
• Aluminization capability without a large capital equipment investment

Packaging, Storage and Handling

• Packaging: Available in quart, gallon and five-gallon containers.
• Shelf Life: One year in sealed container.
• Surface Preparation: Remove all oil, dirt, grease and other contaminants with appropriate degreasing solvent;
  prepare surface by abrasive blasting.
• Application: Mix thoroughly and apply at room temperature with conventional or airless spray.
  (Special formulations are available for dipping.)
• Curing:
  • Ct-33: Air dry about 10 minutes; pre-bake at 140 to 180°F for about 15 minutes; cure at 350°F for 30 minutes.
  • CT-33H: Air dry about 10 minutes; pre-bake at 140 to 180°F for about 15 minutes; cure at 600°F for 30 minutes.
  • CT-33M: Air dry about 10 minutes; pre-bake at 140 to 180°F for about 15 minutes; cure at 450°F for 30 minutes.
• Clean Up: Uncured compound may be removed from spatulas, trowels, other tools with water.
• Safety: Handle in accordance with material safety handling instructions.
